Comment(by rlm):
I think I am seeing this on centos32 on boxen. On this machine, the
trouble is that the walltime is somehow severely messed up.
{{{
sage: walltime()
1256774719.748621
}}}
*Exactly* ten seconds later:
{{{
sage: walltime()
1256774720.2823999
}}}
The difference is only 0.533. At that rate, what is supposed to be a 180
second doctest would take 3,374 seconds.
I'm noticing other strange behavior here too. To debug, I had the code
writing to a file. When I kill the doctest, I get my terminal back. But,
in the other terminal which I am using to "tail" the file, I watch things
continue to be written. Also, running the doctest for one minute, and
sending a keyboard interrupt, gives the following:
{{{
wst...@centos53-32:/tmp/wstein/farm/sage-4.2.1$ ./sage -t -long
devel/sage/sage/groups/perm_gps/partn_ref/refinement_matrices.pyx
sage -t -long
"devel/sage/sage/groups/perm_gps/partn_ref/refinement_matrices.pyx"
KeyboardInterrupt -- interrupted after 3.99422097206 seconds!
[4.5 s]
----------------------------------------------------------------------
The following tests failed:
sage -t -long
"devel/sage/sage/groups/perm_gps/partn_ref/refinement_matrices.pyx"
Total time for all tests: 4.5 seconds
}}}
Huh!?!
